The caller didn't allocate space for ofn->lpstrFile so it left it NULL in the
structure, then it was not filled due to line 2652. Currently the code assume
the variable was set and use it anyway leading to a crash. A correct fix would
be to avoid using ofn->lpstrFile and use lpstrPathAndFile directly after proper
unicode to char convertion.
